Study of the CAE system for product development

The objective of this study is to propose a methodology by witch to establish the CAE (Computer Aided Engineering)system for assisting product development. In general, for new product development designs, the design objects are frequently redesigned on the basis of experimental results. This paper describes a method to establish the CAE system, which possesses and engineering model of a design object in the model database, and refines the model on the basis of experimental results. We have utilized the blackboard inference model to infer the model refinement and the redesign countermeasure. The validity of the proposed CAE system has been verified by developing an active magnetic bearing for a turbomolecular pump.
